To all whom t may concern.'

Be it known that I, FRANCESCO MoN'rroLro, a citizen of Italy, residing at Chester, in the coun-ty of Delaware and State of Pennsylvania, have invented a new and useful Pleasure-Boat, of which the following is a speciication.

This invention has reference to pleasure boats, and its object is to provide a boat arranged to be propelled by the eilorts of the occupant or occupants of the boat, the hull of the boat being of the catamaran type, whereby there is offered but little resistance to the progress of the boat by the water, but the boat is particularly stable.

In accordance with the invention, the boat is provided with two connected hulls in parallel relation and suitably spaced apart to give ample beam, whereby danger of capsizing is practically eliminated so that the occupants of the boat may be considerably elevated above the level of the deck of the boat, thereby avoiding wetting the occupants, of which there are usually two, while the beams of the individual hulls are narrow and consequently the boat may make its way through the water with relatively little resistance from the water.

The invention contemplates the use of bicycle drive and continuously driven ratchet mechanism imparting rotative movements to a propeller.

The invention will be best understood from a consideration of the following detailedl description taken in connection with the accompanying drawings forming partof this specification, with the understanding, however, that the invention is not conined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings-- Figure 1 is a side elevation of a. boat embodying the invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a rear elevation with some parts broken away and certain distant parts omitted.

lig. 4 is a vertical cross section about midway the length of the boat, but omitting numerous parts.

Fig. 5 isvan elevation of an elongated lever forming par-t of the driving mechanism.

Fig. 6 is a section on the line 6-6 of Fig. 1, but drawn on a larger scale and confined to certain details of the structure.

Referring to the drawings, there are shown two boat hulls 1, 2 which may be solid or hollow, but preferably made hollow and follow ordinary outlines except that the hulls are long with respect to their beam and may be quite straight along the sides so that the resistance of the water to the forward movement of the hulls is reduced to a minimum. The hulls are held in parallel spaced relation by cross beams 3 at suitable points along the length of the vessel, and these beams may be utilized to support propelling structure in most part over the space between the hulls.

Erected on the forward cross beam 3 are spaced journal bearings 4 carrying a shaft 5 on which are secured a sprocket wheel 6 and a crank disk 7, which parts, however, may be replaced by equivalent structures. Erected on other cross beams 3 to the rear of the forward cross beam 3 are posts 8, 9, it being understood that the boat, as shown in the drawings, is designed to carry two operators, but it will be further understood that if a greater number of operators is desirable the boat may be correspondingly elongated and more posts may be provided. The upper ends of the posts are connected by a longitudinally disposed beam 10 fast to the respective posts and provided with Va forward' projection 11 carrying an upright steering shaft 12 journaled in the projection 11 and provided above such projection with a steering wheel 13. The lower end of the shaft 12 has a step bearing in an appropriate one of the cross beams 3.

YNear the lower end of the shaft 12 it has fast toit a pinion 14 meshing with a rack 1'5 on the forward end of a bar 16 extended tothe stern of the` boat and there provided with another rack 17 projecting beyond the stern of the boat and engaging a pinion 18 on the post 19 of a rudder 20. To support the rudder there is provided a bracket 21 made fast to and' projecting from the rear cross bar 3, or this bracket may be supported in any other appropriate manner, the arrangement being such that upon turning the steering wheel 13 the rudder may be moved to one side or the other, or may be held straight ahead in the longitudinal center line of the structure. The bracket 21 carries a guide 22 for the rear rack 17 and other guides may be provided, wherever advisable, along the length of the bar 16.

Carried by the posts 8 and 9 at a lower level than the bar 10 are other longitudinally arranged bars 23 in parallel relation, as shown in Fig. 4. Journalediu the bars 23 and extending transverselyl thereof are crank shafts 24, 25, each provided with cranks and foot pedals 27 which may be of the usual bicycle type. rPhe crank shaft 24 carries a sprocket wheel 28 and the crank shaft 25 carries a sprocket wheel 29. Extending between and engaging the sprocket wheels 6, 28 and 29 is a sprocket chain 30 for transmitting motion from the crank shafts-24and 25 to the shaft 5 and from the latter to the crank disk 7.

.Near the sternflofthe boat structure there is a; shaft 31 extendingV from one. boat to the other across the intervening. space and supported by brackets 32 on the respective boats at their adjacent faces. The brackets 32 may be utilized for stiil'ening the post 9 through-brace bars 33, each fast at one end to a respective bracket-32 and at the other end to the rear end of the post 9 close to the upper end thereof. The shaft 31 carries two ratchet wheels 34,` 35 respectively, and intermediate of the ratchet Wheels the shaft 31 has mounted thereon a hub end 36 of a. lever 37, shown separately in Fig. 5. This lever extendsthrough slots 38 in the posts 8` and 9.,.the slotlin the post 9 not being shown in the drawings but corresponding to theslot 38 and the post 8. The lever 37 is continued forwardly to the crank disk 7. andis there connected to the crank disk bya link.39. At intermediate points in the length. of .the lever 37 are lateralV extensions 40,.41,in which are formed slots 42, 43 respectively, curved on an arc of which the axis of the hub 36 is the center. The slots 42'and 43 .are so located as to be traversed bythecrank shafts 24 and 25 respectively thus permitting the lever to rise and fall about;the shaft 31 as an axis to an extent determinedbythe sizeof the crank disk 7.

Mounted on.. the post `8 is an operators seat 44 and .mounted en the post 9 is an operators seat 45. The seat 44 is adjacent to the steering WheellB and the seat 45 may have adjacent toit on the'v beam 10 a handle bar 46 similarto. a bicycle handle bar.

The ratchet wheels 34 and 35 have their teeth on the outer faces adjacent to the outer periphery and the teeth of one wheel are oppositely directed to those of the other' Wheel. 0n the inner face of each Wheel 34 and 35 is a circular series of bevel gear teeth 47 meshing with a bevel pinion 48 on opposite sides of the latter. The pinion 48 is fast to a shaft 49 journaled in a bracket 50 fast to the stern portion of the two boat hulls and extending from one to the other. Fast on the shaft 49 is a sprocket Wheel 51 connected by a sprocket chain 52 to a sprocket pinion 53 on a short propeller shaft 54 carrying a propeller Wheel 55 at its outer end and mounted in a journal bearing 56 supported by arms 57 rising in divergent relation and made fast to the rear or stern end of the boat hulls 1 and 2.

The lever 37, at a point removed from the hub 36 by a distance somewhat greater than the radius of the ratchet wheels 34 and 35, is traversed by a rod or bar 57 a. Pendently carried by the bar 57a arc pawls 58, 59, urged toward each other by a spring 60 common to both. The pawl 58 at its lower end is provided with a lifting tooth 61 and thepawl 59 is provided at its lower end with a pushing tooth 62. The ratchet wheels 34 and 35 have correspondingly arranged teeth 63 and 64 respectively. The arrangement is such that when the pawl 58 is raised the tooth 61 will enga e a tooth 63 and turn the ratchet wheel 34 in one direction 4while the pawl 59 pushes Ithe ratchet wheel 35 in the opposite direction. Since both ratchet wheels engage the pim-on 448 on opposite sides thereof, the alternating movements of the ratchet Wheels in opposite directions cause a continuous movement of the pinion in one direction, which is the direction to propel the boat forwardly through the sprocket Wheel 51, chain 52, sprocket wheel 53, shaft 54 and propeller 55.

Two operators occupying the seats 44 and 45 may readily actuate the sprocket chain 30 and by Way of the lever 37 cause the rotation of the ratchet wheels 34 and 35 oppositely with a step-by-stefp motiomwhich, however, is translated into a continuous rotary motion by the pinion 48 transmitting like motion to the' propeller 55. The operatorusing the seat 44 is enabled to steer the vehicle by means of the steering Wheel 13,'

shaft12, pinion 14, racks 15 and 17 of the bar 16,p'inion '19 and rudder 20. The steering wheel V13 also acts as a steadying means for the operator occupying the seat 44. The operator occupying the seat 45 is steadied by the handle bar 46.

The arrangement is such as to utilize the propelling power of a plurality of operators and'this may be done as easily as two o'per-` ators can propel a tandem bicycle,l except that the resistance of the water renders the work somewhat heavier." The boat will travel more steadily than a tandem bicycle, since no balancing 1s required because of the wide beam of the vessel due to its catamaran characteristics.
